技術(shù)要求  Technical Requirements

按國標(biāo)GB/T20567-2006執(zhí)行。按化學(xué)成分不同分為兩個(gè)牌號。

Conduct as per the National Standard GB/T20567-2006. There are two

classes according to different chemical composition.

密  度  Density

釩氮合金的表現(xiàn)密度不小于3.0g/cm3

Apparent density of vanadium-nitrogen alloy shall not less than 3.0g/cm3

粒  度  Particle Size

釩氮合金的粒度應(yīng)為10mm-40mm,產(chǎn)品中小于10mm粒度不大于總量的5%。

根據(jù)用戶要求，經(jīng)供需雙方協(xié)商并在合同中注明，也可供應(yīng)其他粒度要求的釩氮合金。

Particle size of vanadium-nitrogen alloy shall be 10mm- 40mm, weight of products with particle size below 10mm shall not exceed 5% of the total weight.

Vanadium-nitrogen alloy with other requirements on particle size can be supplied if users have requirements and that is indicated in the contract through negotiation by both parties.
